Component Supply Apparatus Gate Control for Tape Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component mounting systems face challenges in preventing wrong insertion operations of supply tape, leading to inefficiencies and interruptions in the manufacturing process, as they cannot reliably ensure correct mounting of components on intended apparatuses and carts.
Innovation Solution
The system incorporates a component supply apparatus with an insertion gate section that opens and closes based on read information from bar codes, using sprockets and sensors to guide and detect the supply tape, ensuring correct insertion and automatically switching to alternative tapes when the original runs out, thus minimizing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bar code data is collated and verified, then wrong insertion operations are reduced, but the insertion section remains always opened allowing potential wrong insertions
Solution Approach 1:
The insertion gate is opened in advance before the supply tape is actually needed, based on predictive judgment of when the tape will be required. This allows the tape to be ready for immediate use while maintaining security by closing the gate when not needed, preventing wrong insertions while ensuring operational readiness.
Solution Approach 2:
The insertion gate dynamically changes its state between open and closed based on real-time operational conditions. The gate opens when a supply tape is to be inserted and closes when not needed, creating a dynamic security system that adapts to operational requirements rather than remaining statically open or closed.
2Productivity
If supply tape is continuously available, then operation rate is maintained, but wrong insertion may occur when multiple tapes are present
Solution Approach 1:
The insertion gate acts as an intermediary mechanism between the operator and the supply tapes. It controls and mediates the insertion process by being opened only for the specific apparatus requiring a tape, preventing operators from accidentally inserting tapes into wrong apparatuses even when multiple tapes are available.
Solution Approach 2:
The system uses feedback from bar code collation and verification to control the state of the insertion gate. The gate receives feedback about which apparatus needs a tape and adjusts its open/closed state accordingly, ensuring that tapes can only be inserted into the correct apparatus while maintaining continuous operation capability.
3Reliability
If insertion gate is closed when no supply tape is mounted, then wrong insertion is prevented, but tape insertion becomes difficult when needed
Solution Approach 1:
The insertion gate is opened in advance based on predictive judgment of when a supply tape will be needed. This preliminary opening ensures that the gate is already open and ready for tape insertion when the operator needs to load a tape, eliminating delays and making the insertion process convenient while maintaining security when closed.

AI summary
There is a need for providing an electronic component mounting apparatus, a component supply apparatus, and an electronic component mounting method capable of reducing inadvertent insertion of component supply tape and ensuring high reliability or capable of reducing wrong insertion of component supply tape, supplying new electronic component tape, and ensuring a high operation rate. Supply tape is inserted into an insertion entry of a component supply apparatus. An electronic component mounted on the supply tape is absorbed and is mounted on a printed board. Information about the electronic component mounted on the supply tape is read. Based on the read information, the component supply apparatus for inserting the supply tape is selected. The insertion entry is opened while it is closed when no supply tape is mounted.
